lis the lower cross-slide,which is adapted to reciprocate in a groove inthe upper cross slide, but independently thereof. The upper Across-slideis actuated hy a. lever, Il", pivoted 'to the sliding plate ll.

Each end ofthis lever carries a pin and rollenthe rear end engaging the` upper cross-slide, (see Fig. 19,) and the front. end engagingacain-plate, K. Secured Kie anopen -space eut ont from the surface of the cam-plate, having a straight wall, K2,

" upon the right side, and an lrregularcainwall, K3, upon the left side.

K* is a switch-cam pi voted in the open space and provided with a cam wall, K", which forms, with wall K, a groove in which the roll 'slides inits forward movement. ,The normal 44position of the switcheani is as shown in Figs.

12 and i3, in which position it is held by a spring, Kr?, having a pin atits end which passes through an opening in wall K2.

In Fig. 12 the sliding plate I is shown at its extreme forward positionl As the plate nieves hack ward the roll upon lever 1" moves` yalong the camwall K3, and between said cam'- wall and the cam-wall of the switch-eam,which is moved outward against the power of spring K". This movement of lever 11 carries the upper cross-slide inward, as indicated in Fig. 13, which also shows the sliding ,platel' atthe opposite extremity ot' its movement from that shown in Fig. l2. From the positionr shown in Fig., lthe sliding plate begins to move forward. AThe switch-cross having resumed This block reclpio l its normal position'fithe instant the roll passed Abeyond it,the roll inthe return movement will pass along its opposite side-i. e., in the straight slot formed by the back ofthe switchcaln and the straight .wall K'l of the open space in the complete.

' vI12 is an arm projecting outward from lever 1*, which hears against bridge l when the y.return movement ofthe sliding plate is nearly nished, and actsrto carry the forward end of lever 11 over against cam-wall K, and to return-the upper cross-slide to the position shown in Fig-12, the switch-cani being cut away, as at K10 to permit the roll to pass over against the wall K3 again. It will thus be seen that the return movement of the crossslide must take place in a much shorter time than is allowed for the forward movement. The'lower cross-slide is provided on its under side with a roll, i, which bears against a cam, K7. v

K is a spring recessed into the upper crossslide and bearing against a projection, K9, on the lower one, which acts to hold said lower slide against cam K7. It will thus -be seen that as the sliding plate I moves forward and backward reeiprocatory movement will be imparted-to said lower cross-slide by cam K7; but such movement will Aloe whollyindependent of the reciprocation of the upper cross slide.

L isaleverwhich l term the needlepresser lever, which is pivoted in a yoke, LQ the' shank L2 of which isjonrnalcd in a standard, L, seen red to the sliding plate. The forward end of this lever is provided with a ball, L4, which engages in an undercut circulargroove, L5, in block L5, whichis attached to bridge I. The shape of the block and groove are clearly shown in Fig. 16, the object being to Aimpart hoth vertiealand horizontal vibratory motions tolever L.

L7 is the presserspring, which .is attached to the rear end of lever L. r"his spring is preferably a bow-spring, as shown in Fig. 19, the point of which passesintoa slot, LS, inthe narrow portion of the hopper. separating the Shanks oi' the needles, as shown in Fig. 19, straightening them up and pressing them down, as will be again referred to. rSuppose the sliding plate l to be at its extreme back- 'ward position, leverL will he at the rear en d of the groove, as in Figs. 13 and 16, andthe point of spring-LT will he out .of slot U. `As theysliding plate' I moves backward-i. e., toward the front ofthe machi ne-Jno movement' of lever L takes place while the ball remains in the straight portion l of the undercut groove. After passing this portion of the groove there is an oblique portonl in the groove. As the groove is undercutl to cor,- respond in shape withthe ball, it is apparent that theball must remain in the/groove, no matter how inuch it may vary either vertically or horizontally from a right line. g The action of theoblique portion of the vgrooveyas the sliding plate moves backward-he., toward the l'ront ofthe machine-is to carry the point ot'springsr lf into the hopper, and between the needles, as shown in Fig. 19, At this moment the hull will have reached the inclined portion l: ofthe groove. As the hall travels up the incline it oi' course acts to depress the rear end of lever L and the presser spring, thus Siraighning up the shanks of the needles and pressingthe lowestneedleinto ihegroove het wcen the shoulder 'al on the upper cross slide and the edge ot' plate i', which is attached to project-ion K, on the lower cross-slide. TheV upper crossslide is out away to form 'shoulder i, and plate lies over this cut-away portion, as clearly shown in Figs. 17, 18, and 19, said cutaway portion oft-he upper cross-slide formingl the bottom of the groove, into which the lower needle is forced. The downwardpressurc of spring LT continues while the hall is traveling up the incline, and is held while the hall is in the straight portion Z3, and until the ball has begun to travel downthe incline in the forward movement of the sliding plate. -As the hall travels down the incline the rear end ot' lever L is lifted, the presser spring being made sufficiently elastic to yield untilit is drawn out by the action of the oblique portion ot the groove which throws the rear end of the lever to the position shown iu Fig. 13. Thel pressehspring is then .forced intel-he hopper hetweenthe needle, again, and the action of straightening `up the shanlis and 'pressing' a needle .down into the groove'between'the crossslides is -epcated,.as before, eachY recip rocation of the sliding plate imparting four movements to lever L. Y,

'MT is a springfcoiled around the pivot ofthe swinging arm, whose ends bear, respectively, against thestandard andv the swinging varm, and which acts to hold the swinging arm against pin i2. `As the action of spring Mis lto hold the presser-,footdown upon plate i',

it follows that 'as the plate moves forward 'toward the leftthe' presser-foot will move with it,'and as soon as the needle cornes under the p'resserfoot` it will be held thereby and rolled i until the gizooves of the needle shall he at top and bottounf'asclearly.indicated in Figs. 18 and' 19. After the operation of rolling by the spring presser-'foonwhich'l term registering the needlethe accelerated motion ofthe upper .crosslslida as .already described, takes place'iandtheneedleisrlined up in the groove, ready' to be grasped hy the chuck. .f

At the same time there must be no .friction upon the needle, otherwise the chuck might not retain it.

" As it is sometimes desirable to change the vpressure on the needles iu changing from large 4to sin'allgor vice versa. l have provided asetscnemlM", in arm lM?, hearing against the swinging arm, the adjustment of which determines the .pressure of the footupon' the nee-y die. After the needle has been grasped hy the chuchaswill be more fully describedsthe for- `ward movement of the sliding plate begins,

leaving the needlein the chuck. Assoon as the plate 'has moved back far-enough to clear the needle the return movement of the cross-slide E lrepresents' a'series of chucks upon the l needle-carryingv plate' E, whose spindleslfl'l are free to rotate in .hearings E5, secured to said plate.-V l These chucks may he ot any preferred While IOOV I KVO construction; but I preferably split the end of the chuck, provide an internal socket to receive the shank of the needle, and an outward bevel at the. outer end, which is engaged by a corresponding bevel upon a'cap or sleeve, E4, which acts to close the jaws upon the shank ofthe needle as it is forced forward by aplaincd..

E represents a inv guides EN. i

E is a gage at the point of the presserbar, which is provided with a groove (not shown) in which the needlerests, and may be adjusted up or down to regulate the pressure of the points of the needles upon the stones.

E12 is a lever -pivoted to the underside of table E and Working in a slot (see Fig. 4) in said table. The upper end of this lever engages the presserbar, as at E, and at its lower end is provided with a roll, E, which at a certain stage Iin each revolution of the table engages a cam, A, upon table D, the function of which will be more fully explained.

E15 is a spring connected to lever El2 and to presser-bar adapted to slide the under side of plate E, which acts to draw theclower end of said lever inward and to throw the upper end, and with it the presserbar, outward,'as`shown at the right inxFig. 4. In this position thegage is pressing upon the needlejust back of the eye, and which holds the point of the needle firmly down on the stones. The pressure upon the needle may be changed by adjusting' gage E up or down. The outlines offcams A5 and `A6 are indicated in Fig. 3. The chucks and presser-bars remain in the position relatively to each other and to the stones in which they are shown at the right in Fig. 4 for three-fourths of each revolutiom-ih e., while a needle in any one of the chucks is being subjected to the grinding action of the six stones, emery-belts, or what` ever may be used.

It will of course be understood that the number of stones and the number of chucks used is not an essential feature of my invention, but the number of bot-h may be varied within reasonable limits without departing from the spirit thereof. In the present instance l have shown eight vneedlechucks and six stones, so

that one chuck will be at the feeding device.

receiving a needle, one at each of the six stones or grindingwheels, and the eighth will be at the extractor delivering a finished needle. Aft-era chuck, in the revolution ofthe table,has passed the laststonelever E12 comes in contact with cam A` upon table D, which forces the lower end outward-against the power of spring E, and consequently carries the upper end of said level-,and with it the presser- 'E12 is acted on by cam A6 lever E7 cornes in Contact with cam A5, also upon tableD, which forces the lower end of said lever outward and vthe crotched end (which bears against the flange on sleeve E) inward against the power of spring E5,'thus opening the chuck and allowing the needle to be seized by the extractor, the constructionof which will presently be explained. Camv A5 is nollowed in, -as indicated in Fig. 3, so that during the instant of time that elapses after the nished needle vhas been removed by the extractor, and before a new needle has been seized by the chuck, lever E resumes its normal position and spring E5 forces the sleeveforward to close the chuck. This removes the pressure ot shoulder E against the bearing and ofthe lever against the flange on the sleeve, leaving the spindle free to rotate in its bearings during the time that the chuck-registeringk mechanism, which vwill presently be described, is acting. After the chuck-registering mechanism has acted the chuck is opened, as before, and seizes the needle, as indicated at the left in Fig. 3. At the instant that the shank of the needle has entered the chuck lever ET has reached the end of cam A5, which is abrupt. This allows spring E5 to-carry the sleeve forward, thus gripping the needle rmly and leaving lever E7 at its-normal position. Cam AG is beveled vat both ends, but its outer or bearing surface is a curve concentric with the curve of the table, so that the forward and backward movements of the presserbar are not abrupt,

and during the ti nie-that elapses between said movements-. e., while the tinished needle is being removed by the extractor and the new needle is being seized by the chuck-both lever and presser-bar remain at the position indicated at the left in Fig. 4. The presserbar does not advance to the position in which it is shown at the right in Fig. 4 until just before the new needle is acted upon by the first stone.

El is a crank at the inner end of each chuckspindle,having a pin, E, which is adapted to be acted on by the chuck-registering cam, and also to engage in notches F7 in flange F6 upon plate F.

E1R is a spring. coiled around each chuckspindle, the end of which is attached to the crank and acts to hold the crank-pin down upon the surface of ange FG, or the chuckregistering cam, as may be, forces the pin into notches F7, and also acts to force the cranks outward on the spindles, keeping notches E19 in the cranks in engagement with pins E2 through the ends of the spindles. (See Fig. 6.) U

E represents pinions on the chuck-spindles, `which engage short' sections of gear-teeth B, which are att-ached to plate B.

As stated above, plates F F3 are-rigidly secured at thetop of shalt F, being supported by bosses FB between the plates through which screws pass. The shaft is oscillated by means of a crank carrying a roll which bears against cam G'. More than half ot' the periphery of this cam is provided with not-ches or depres sions into which the roii drops, thus oscillating shaft F and the parts carried thereby. rlhis cam is so timed as to make afuli revolu` tion foreach forward movement ofthe needlecarrying table, the curi-'ed'portions of the periphery of the cam (shown only in edge View) being in contact with the roll during that portion of ythe revolution of each chuck in which the tinished needleis removed by the extractor and the new needle received from the cross slides. Just before the new needle reaches the first stone the crank-pin E" drops intothe first notch in iiange F5.

As stated above, table D, which carries the grinding and poi ishing wheels or emery-belt-s, is arranged to vibrate, but has no rotary movement. The vibratory movement of this table is imparted by a crank carried by shaft G, whose pin G" engages block GT, which reciprocatcs in slot ll in the qtabie, the effect of which is to give a backward and forward movement to table i) for each forward movement ot the notarile-carrying table E. The movements oi' the two tables and plaies F il, carried byshai'i: F, are so timed relatively to each other that before a needle has reached the liz-st stone the presser-bar will have moved forward lo hold the needle against thestone and cran k E" will have drop pcd into the first notch in ilange lfl. J ust beiore the needle reaches the sione/.thc forward movement of the needle ceases, and the backward movement. of the vibratingtable takes pince, the needle-carrying table remaining,r stationary while the Stone or cmcry-belt is moved bacxward under the needle.` l.Vhile this backward movement of' the stone is taking piace the engagement ot' crank pin iii" in the notch Flimparts an oscillatory movement to the chuck and the needle carried tiiereby,wliich causes the point to roll back ward and l'orward on the faire ott-he stone, grimiing` oli' the corners more or less, as may bc desired, the amount of oscillation imparted lo the noodle determining the shape ofthe point. Ai' the instant that the stone has passed from under the needle the forward movements ol' both tables take place, table E moving forward sufficiently to carry the needieto the next slone,tabie D merely resuniingits former position. lVliaie the tor-ward movement ot' the needle-carrying plate is taking piace pinion il on the chuck-spindle engages the section of geartepth 133. (See Figs. 7 and 1l.) The crank-pin is lifted out of notch FT, but is prevented from being carried over byplate if, between which and the top ot the tlange it rides during the forward movement. As the spindle is forced to turn by the engagement of the pinion with the section of gear-teeth, but, the crank, alter the piu is lifted ont of the notch,is held against further rotation by plate F, it follows that piu El will be forced out of notch E, thus forcing the crank inward against the power of spring Elin which position it is held until the spindle has made a half-revolution, at which instant the pinion 7o will have passed thelast tooth in the section of gearing, and spring E will again force the crank forward, causing notch El to engage pin El". An instant later the crank-pin drops into the next notch in flange F6, and the second stone is ready to pass under the opposite side of the needle from that which was acted on by the lirst stone.

As stated above, any number of stones or emery-belts and any number of needle-chucks 8O may be used. In the present instance I have shown eight chucks and six stones, so th at. one chuck will be at the hopper receiving a needie, one attheextractorsurrenderinga needle,

and-there will be a chuck with a needle at each of the six stones. The stones I preferably arrange in pairs', so that the needle has to be turned but three times. For example, a needle is acted on by the coarsest stone. It is then turned and its opposite side go acted on by asimilar stone. It then passes without turning to a liner stone, alter which it is again tnruedand` the opposite side ground on a fourth stone similar to the third, and so on, no matter how many stones maybe used,

but three sections, B", of gear-teeth being necessary in thearrangement I .have shown to subject both sides ofthe point of every needle to the grinding action of each pair of stones,

or, as stated above, emery-beits maybe snb- 10o st ituted, if preferred, the use of both stones and belts being old. These stones when in use revolve at a high rate of speed, Ymotion being,r communicated thereto in any suitable manner. drum` A3, by means of belts D3, running over pulleys N N N2. The style of point to be ground is determined by a cam, B2, which I term the chuck-registering cam. This cam is attached to plate B', and is so located that it im will act on crank E after the finished needle has been seized by the extractor, its action being to turn the spindle, and with it the chuck, into such a position relatively to the needle at the instant it is seized that when-crankpin [i5 E drops into notch F7. the eye ot' the needle will be at the angle relatively to the plane of the stones .which is necessary to produce the desired style of point. It will of course be understood that a new. cam must be sub- [zo grooves being` vertically above the other, it 13o being rolled to this position by presser-foot M. Fig. G is an' edge view ofthe crank and pin in the position shown in Fig. 6. Fig. 7 illustrates the vibration of plates F F3 during I have shown them as driven from a Fig. G iiiustates the cam used in the grinding ofa point, and Figs. 7 and 7" the extremesof vibration of the needle while.

Fig. 9il1nstrates-the chuck# f `registering camV used in making what are knownas cross points, this style of point being ground at a right angle to the ordinary flat point. Figs. 9 and 9"'show the normal position of the needle', Vand also'the position-at which the point is 'ground,the`positions being the same. Fig. 10 'illustrates'the can; .used in making what are known as f reverse-twist points; Fig. 10, the normal position of the needle, and Fig. l()b the positezr'at which the' point is ground.,`

Aftenit has been acted on byv the st stone the needle passes to the extracto Before reaching the latter,

O is a block rigidly secured to fced-table` I, and provided with a dovetail groove, O.

P is a slide having a spline, P'Lon its under side which corresponds in shape with groove 0'.- y

R is the under or fixed jaw. which is attached to or made integral with the slide. The upper jaw, lt', is pivoted between side pieces, R2, upon tho under jaw. A spring, R, between the jaws acts to hold them in their .The shankof the upper jaw extends backward from the pivotal point and is curved downward, forming an incline, R, the .purpose of which will presently be explained.

S is a rock-shaft journaled in bearings S', secured to or :nude part of the feed-table. An amm-S2, )rejecting outward from the inner end of this shaft, bears upon the face of cani v spring, S, coiled around the shaft.

however, theraction of .cam A6 upon iever Ew'bas S is an arm projecting 'rovp the upper end of the shaft, the outer end of which passes un der the upper jaw of the extractor, and acts upon alug, Si, upon the lower jaw t6 give the forward .mov-ement to the extractor, and upon incline R4 to give it the backward movement.

The operation of the extractor is as follows; Cain H is so timed as to :make as many revolutions during one revolution of the needlecarrying' table as there are needlechucks carried thereby, said cam -being laid .out to give one oscillationi. forward and back -ward movement to the rock-shaftduring each approaches the vombra-eter arm Ea is hearing f against lng Si, which forces thejaufs forward, spring E actingto hold them open. At the 'instant that the needle is between the-jaws of needle havingV been released, as stated above) rthe reverse movement Vof the rock-shaft ne gine. This causes arm' Si to bear against incline 'R2 which acts to close the upper jaw down tirrnly on the needie, and at the same time to carry the jaws, with the needle between them, backward away from the chuck.

The cranks at ine inner end of the chucks are in turn acted on by a stationary calm-B, as4 they grasp aneedle,

Having grasped a needle, each chuck in turn passes to the ii'rst gri ndingstone. During the grinding the tahie remains stationary, while the stone moves backward under the needles, whichl meanwhile are `slightly oseiliated by the engagement ci' thecranks with the notches ment is imparted by action of cani G o n crank F, the points ofthe needles being held` down upon the stones hy presscnbars ha.
